TELESPHORE J. BEAUDETTE, OF LOS ANGELES, CALIFORNIA.

AGETYLENE-GAS GENERATOR.

Specification of Letters Patent.

Patented Dec. 10, 1907.

Application filed December 19. 1906. Serial No. 348.547.

. To all whom it may concern:

Be it known that I, TELESPHORE J. BEAU- DETTE, a citizen of the United States, residing at Los Angeles, in the county of Los 5 Angeles and State of California, have invented new and useful Improvements in Acetylene-Gas Generators, of which the following is a specification.

My invention relates to improvements in generators of that type wherein water is fed to the carbid in quantities automatically controlled by the pressure of the gas generator.

One of the many objects of this invention is to provide a generator of this type wherein the control of the supply of water will be sensitive and will operate ositively and efliciently under either a high or a low gas pressure.

Another object is to provide a generator in which the pressure of the gas to the lights is automatically regulated irrespective of the gas pressure in the generator.

Other objects and advantages of the invention will be hereinafter stated.

In the drawings the generator is illustrated in a form for use on an automobile, but it is to be understood that it is adapted for use in other forms of apparatus.

Figure 1 is a perspective view of my improved generator detached from the machine. Fig. 2 is a section on line 2-2 of 1. Fig. 3- is a section on line 33 of A storage chamber 4 is formed by the outer casing 5. In the top of the storage chamber is a water chamber 6, the top of which is formed by a portion of the outer casing. In the top of this chamber is a filling port 7 which is closed by a screw plug 8 which may be removed when it is desired to fill the chamber. Leading from the bottom of the water chamber is a pipe 9 which opens into the water controlllng valve chamber 10 through the casing 11 of said valve chamber, which casing is secured to the outer casing. The outer end of this valve chamber is enlarged as shown in Fig. 2 and has a port 12 therein. Projecting into the enlarged end of said valve chamber is a resilient diaphragm 13 which is secured to the outer casing and also secured to the reciprocating valve 14 which has an opening 15 extending transverselytherethrough which registers or is out of register with pipe 9 when the valve is feeding water or is closed as hereinafter stated. In the position shown in Fig. 2 the valve is fully open. This valve stem passes through an opening 16 in the outer case and thence through a hollow washer 17 and thence through nut 18 and passes through the end of the casing 19 secured to the outside casing, asshown in Figs. 1 and 2, and forms a chamber on the outside of the main casing which I will call the spring regulating valve chamber. Surrounding the valve within this chamber is a spring 20, one end of which bears against washer 17 and the other against a washer 21, which latter washer is secured to diaphragm 13 and to valve 14.

Connected to and opening to the interior of valve casing 11 on the opposite side to pipe 9 is a pipe 22 which leads to and opens into carbid chamber 23. chamber is a sludge chamber 24 and the two chambers are separated by shelves 25 and 26 which preferably project downwardly as they approach each other and preferably terminate near the center of the bottom of the carbid chamber, of which chamber these shelves form the bottom. Shelf 25 is preferably imperforate, while shelf 26 is preferably perforate and projects a little over shelf 25 and terminates slightly above the same to permit the ash to pass down into the sludge chamber. These shelves slope downwardly as best shown in Fig. 3 so that all of the carbid may ultimately be subjected to contact with the water flowing into the chamber through pipe 22 and also so that the ash will be washed into chamber 24. The outer casing formsone end of chambers 23 and 24, and the other end is closed by a removable door 27 which is secured in place by means of bolts 28, provided with wing nuts 29.

The casing is preferably reinforced at the door by a flange 30 and a gasket 31 may be used to secure an air tight and water tight joint at the door. A pressure gage 32 is pro vided in that part of the door which covers the end of the carbid chamber so that the gas pressure may be known. A pipe 33 leads from the top of the carbid chamber to the top of the water chamber and terminates within the closure plug 8, which is hollowed out for that purpose, so that water will not easily enter the carbid chamber therethrough when in use on an automobile and the water may be subjected to gas pressure. Preferably secured to the upper part of the main casing is the service regulating valve chamber 34.

Below the carbid Within this last chamber is the resilient diaphragm 36, to which is secured a stem 37 which passes through a port 38 in casing 35 and exterior said casing said stem carries a valve 39 which, when the gas pressure rises too high closes said port and prevents the passage of gas therethrough. On the opposite side of the diaphragm to stem 37 is a spring 40 which passes through a port 41 in the outer casing and bears against an adjusting disk 42 secured upon the inner end of screw 43, which screw passes through a casing 44 which surrounds said spring and port and is secured to the main casing.

Leading from the service regulating valve chamber is a pipe 45, which opens into a distributing chamber 46. The casing 47 of this chamber is secured to the main casing. Leading from this distributing chamber are a plurality of service pipes 48, each of which is provided with a cock 49 thereon so that any service pipe may be cut out that is desired. These service pipes lead to lamps (not shown).

In the top of the carbid chamber is an outwardly opening check valve 50 which permits the gas to fiov' from the chamber, but prevents its return thereinto. The water chamber and the carbid and sludge chambers are considerably smaller than the storage chamber and the unoccupied space in said storage chamber I preferably fill with acetone acid and ground asbestos 5]. as the use of these materials enables me to store a much larger quantity of gas than I could do without their use. I also provide a safety check valve 52 to guard. against too high pressure in the storage chamber.

In the operation of my device it will be understood that I fill the carbid. chamber with carbid 53 by removing door 27 andv then replacing the same, that when the door is removed I clear out the sludge, and that I fill the water chamber by removing plug 8 and after the chamber is filled replacing the same. I regulate the tension of spring 20 to whatever desired pressure I may wish to have within the storage chamber which is 20 pounds or higher or lower as desired. I also regulate the tension of spring 40 so as to have the desired gas pressure at the lights, which is preferably about four ounces pressure. When there is no gas within the storage chamber valve 14 will be carried by the pressure of spring 20 so as to bring opening 15 thereof out of register with pipes 9 and 22 and. to the left thereof, and no water will be fed into the carbid chamber while it is being re-filled. Now, to start the generation of gas after the parts are all charged, the operator will catch hold of the projecting end of valve 14 and pull on the same until he brings it to register opening 15 with pipes 9 and 22..

After he has permitted suflicient water to flow into the chamber to generate gas suflicient to hold the valve in that position, he re leases his hold on the stem and the further generation of gas increases the pressure upon diaphragm 13 until it carries valve 14 to bring opening 15 out of register and. to the right of pipes 9 and 22, thereby cutting ell the further flowof water. a When a suilicient quantity of gas is used. to reduce the pressure so as to permit the spring 20 to force the valve to bring opening 15 again into register with pipes 9 and 22, water is again permitted, to flow into the carbidv chamber to gcnerat e more gas. It will be understom] that as long as there is a sullicient quantity of carbid in the carbid chamber the supply of water flowing through the valve will always be sullicient to keep the pressure high enough to cause the water to be cut oil by the movement of the valve to the right, and. that it is only moved to the left after the supply of carbid in the chamber has become exhausted, whereby the operator can always tell by the position of the outer end of valve 14 whether the carbid chamber needs refilling or not.
